I'm on the same pill, I believe it says if you miss one, take it as soon as possible and then take the next one at the normal time. Dunno about two days though. You might get a little bleeding but I'm not sure, it didn't say in the leaflet. Since it says you should be protected from pregnancy 7 days after missing one, I'd assume that's when your periods will go back to whatever they're normally like on the pill.
